I have a MyUserControl in which I have Button1 and Button2 buttons. I need to "delegate" that button clicks to the MyUserControl's Button1Click event and Button2Click event respectively. Below is a stub I don't really know finishing...
Private WithEvents Button1 As Button
Private WithEvents Button2 As Button
Public Custom Event Button1Click As Eventhandler
AddHandler(ByVal value As EventHandler)
AddHandler Me.Button1.Click, value
End AddHandler
[Code] .....
I wonder if I need the WithEvents in the buttons declaration, and how to achieve the RaiseEvent part...
I have a winform with a wpf usercontrol on it (ElementHost1). The usercontrol contains only a button. How can I know when the wpf button has been clicked in my winform? How can I "redirect" the events from wpf usercontrol to winform?
Ran into this while converting a VB.NET interface to C#; the VB version defines an event which doesn't conform to the typical (object sender, EventArgs e) signature:
I have a gridview with button in one column.I want to redirect to another page along with parameters on clicking on button.Is there any option to do this in rowdatabound event in gridview.
Background: I have a GridView which gets populated from an SqlDataSource via DataSourceID. The rows show some summary data from an SQL View. Upon clicking a row, I would like to take my user to another page with a DetailsView control which gets populated with the full set of values from the DB related to the row clicked. My user should be able to edit the data, download files associated with the record, and create a new record of a different type based on said data.
Error: All examples that I've found for Clickable GridView rows end up with some variation of the error Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page.
I always get worried and my layout when i code. I always get myself in a flap when coding and worried i should be doing it different.What i am going on about is not the code it self. But where i actually put the code.
What i am thinking about is functionality (does it matter if formload code is at top/bottom/ or even middle)
And read ability. Do i put all button events into regions?
I believe I may have already posted a much longer explanation of this , but its driving me spare!!! I have several pieces of code that click buttons thru sendmessage commands, all the code works fine in Windows 7! But I put the app on WindowsXP and only some of the buttons will work,
I have made an click event for a button which creates buttons dynamically and I added events to the dynamic buttons by using addhandler but it says it the button is not declared. Here is the code for dynamic buttons:
Private Sub MenuBtnNew_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MenuBtnNew.Click
I'm just wondering how I can make a custom button, but have it inherit the regular button? I just want to change the way it looks, and change the button hover/click events
Is it possible to have multiple click events for a button based on the button text? In other words, if I change the button text can i create a new click event based on that text but use the same button?
for example:
button1.text starts as "steel" button2.text starts as "brass"
If I click button1 again a string would then be added to a textbox and the process would start over again. can I have a different click event or would I need to put an If/Then or Select/Case in the sub to handle this? I have 10 buttons I would need to do this with and each needing at least 3 different choices for each depending on the previous button press.
I want to add a custom property to a button in window form. Currently i am using following code to create my logic. but i want to create an enum value for a button control.
I have created a simple custom control - we will call it a "panel with buttons". Here is how I instantiate it:
[Code]....
So what I wind up with are multiple instances of my panel. Each of these panels has a button on it called Button1. My question is - how do I capture this button event in a way that I will know which panel index it came from?
In the custom control there is only the Button1_click event - and when I click on it in any of the multiple panels I manually instantiated the event does occur, but how I can tell which one of my instantiated buttons were clicked...
in a winform, in vb net,I have a list view with hoverselection set to true. I start a drag and drop operation when the mousedown event is fired, but it's fired only when i release the mouse button on the control or on the dropped control! is it a normal behavior?
I have an application similar to calculator, with button from 0 to 9, Enter and Clear. I made it possible to use the buttons by clicking on them and also by using numpad, like shown below: Private Sub Form1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
I have three events to fire on button click. after running the first event i want to wait for 30sec to wait for nex event to fire. how i can wait( i mean looping for 30 secs).
I found some threads talking about this.. but when I follow the thread on where to do it.. it must be talking VS2005.. cause on vs2008 in project properties -> application tab-> I dont see View Application Events button. so I assume its moved in VS2008 ? I did find some code I guess to do the same thing.. but I wanted to make sure I do it correct.. since I have an app that a client is running and they keep getting framework exceptions and I have no clue where its coming from.
I have a windows applications. Form 2 is child form of Form1 . Basically when button on form2 (child form) is clicked, it raise an events, which writes something in testbox on form1 (parent form). This is my code
parent form form1
Public Class Form1 Public mycount As Integer
[CODE]..............
This is the first time I am tring to use events.. I am not sure what's going wrong.. the textfill event is never called from form1.
Problem that you may have when dealing with two objects that are raising some events. Here, to make it obvious, I am closing the form, but the problem can be experienced with any other 2 classes event. First, what is the problem !
Let suppose that by pressing a button, you want to raise a custom event, then execute a method and then close the form
In that case, you may use a code similar to this
Event BeepIt()
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click RaiseEvent BeepIt()
I have master page in ASP.NET. I have added two asp controls to master page i.e. _EmpDROPDOWN and _findBUTTON.I have one content page.

In my program i have a log in screen, what i want to be able to do is to be able to load the next page on the press of the "Enter" key as well as a button.
I'm currently debugging a form that sets a flag when the mouse button is pressed, then clears the flag when the mouse button is released. As long as the mouse button is pressed, the user can move the mouse around and a few things happen depending on where they move. One of the things that happens is that a timer starts, or stops, and a few things change color depending on the mouse position. The timer starts when it should, then stops when it should, but once stopped, it is not re-starting when it should. I can verify that MouseMove events are getting through, because coloring changes as I move the mouse, as it should. This would be a simple thing to debug...except that it requires the darn mouse button to be down, and it uses the mouse move event. Anybody who has put a breakpoint in a mouse move event handler knows the issue: There are THOUSANDS of them. Worse yet, since the mouse button is necessary for switching to the IDE, as well as setting a breakpoint (technically, a keyboard shortcut could do this if I could shift focus), I can't wait for the problem to happen, then switch to the IDE and set a breakpoint to see what is happening then.Does anybody have any tips or techniques for debugging in mouse move events when the mouse button is down and has to stay that way? As it is, I'm going to have to write some funky code into the method just so that I have a place to get a breakpoint when I need it without breaking on every one of the mouse move events.
I am trying to create a simple program that will receive input from 6 buttons entered 6 times (That is, from a row of 6 buttons, pressing 6 of them in order) will produce some mathematical results. Depsite being new to the world of programming, I managed to write some code in VB 2010 Express that gets me to getting the 6 buttons of the first set using a for loop. However, I've been unable to make a difference between the buttons That is, each button will do that same thing each time it is pressed. This is the code I have so far:
Public Class Form1 Dim StartButton As New Button Dim QuestionSet1() As String = New String() {"Ardor", "Passion", "Vigor", "Talent",
I have been trying to implement the jQuery weekcalendar using .net. What I can't seem to figure out is why weekcalendar states events.events is undefined after I make an ajax call to a webmethod I created which returns JSON. Below is the relevant code:
How can rightfully declare these in VB.net , in my coding it's highligted errors on these declaration.
